Most any reloading manual will give you the data. IMR 4895 can be used in just about every rifle cartridge except the .398? I understand the phenomenon of the fingers not being connected to the keyboard-brain synapse and you meant to say .308.
For liability purposes I wouldn't recommend that anyone give a specific charge designation over the net. Just go to any reputable reloading data book and experiment, thats' the fun of reloading.
As for the .398 cartridge I would recommend that you inform Fienstien and Schummer that you have developed a new anti personnel vehicle weapon and suggest that they introduce a bill to ban it, should keep them busy and out of our hair for a while. At the same time make them look like the idiots that they are.

Do you want 4695 loads for .308 or 4895 loads for .398? Just kidding, I have often wished for a numchecker application like a spellchecker.

Your best bet is to go straight to the source. Check out www.imrpowder.com
They should have some good loads for these calibers. There are too many variables peculiar to each any every gun that may make someones "favorite" load a deadly load in another gun.
